Make your spears thinner by cutting them in half if you feel they are too thick.
Place the flour in a shallow dish and mix in the onion and garlic powders, and add salt and pepper to taste.
Whisk the eggs in a separate shallow dish.
Place the panko breadcrumbs in a third shallow dish.
Coat the pickle spears first in the flour, dip in egg, and finally roll in the Panko breadcrumbs until fully coated.
Let them sit for 5-10 min to help the coating adhere better during frying.
Heat the vegetable oil in a large skillet over medium-high heat (test the oil dropping a few breadcrumbs. They should sizzle immediately when the oil is ready)
Fry the pickle spears in batches, being careful not to overcrowd the skillet. Cook until golden brown, about 2-3 minutes on each side.
Drain excess oil by placing the fried pickles on paper towels before serving. Serve warm with ranch dressing or your favorite dipping sauce.
